1st. implementing activitypub or any other federation protocol is quite a task. also in my opinion it does not need to be federated. there are basically no benefits, except convenience for the users.

2nd. it’s open source. if you don’t like the way it’s monetized, fork it and make your own. it’ not foss.

probably some error in the firmware. most devices wonn’t boot if you flash firmware for the wrong hardware revision.

between neutral it’s 230V.Between two phases it’s 400V.

3-phase 230V 16A is standard here. but you can get up to 30A if the wiring allows it. I’ve never seen a house with only 1 or 2-phase.

Something like Baldur’s gate with good ol’ realtime with pause. Baldur’s gate 3 is a great game, but playing it feels like divinity and not baldurs gate

at my parents house the is a 14kw heat pump that does heating and water and it’s not an industrial heat pump. you can get them from daikin, but they need three phase ac.
